I'm using this MCS-T on my .308. I really like the shape of the stock and although it lacks a vertical grip, it's incredibly comfortable to shoot prone.

Here it is as it sits now...

And here you can see the shape a bit better, this was before it's "make-under".... grin

The stock pack isn't necessary to get my eye into a good spot in relation with the scope, but I kind of smash my face into it and it's like shooting off a pillow.

Bedded and floated, it shoots really well. I think you'll love the Manners.
